The range of the intermolecular potential determines whether or not stable liquidvapour coexistence is possible. We argue that for short range attraction, the liquidvapour transition may be located below the sublimation line. Under those conditions, meta-stable critical fluctuations may enhance the rate of crystal nucleation
